title PCIS: a piece-based construction information system on the world wide web
source Automation in Construction 6 (4) (1997) pp. 287-298
summary This paper describes a piece-based construction information system organized as a hypergraphic virtual environment on the World Wide Web. An array of cubes on the site's animated splash-page acts as a directory to a collection of data-theaters that give this information its virtual form. A mouse click on one of these cubes leads to an orthographic model of the object to be constructed. This model is an index to a database of scaled drawings, animations, and specifications. The index is hypergraphic because a click on the image of one of the pieces of the model leads to a data page that provides information about that piece in the context of its assembly. Panels surround the index to act as an interface to projections of the pieces of the object. These projections include elevations, plans, slices, and dimensioned details. A click on the elevation-panel leads to information on finishes, framing, and construction of each face of the object. From above, the plan-panel shows roofing, framing, floor plan, foundation layout, excavation, and utilities as an animation of the construction process. There are also animated slice-panels that cut through the object to give heights and materials. A click on one of these panels leads to two-dimensional drawings and details of the actual construction. The orthographic index morphs to a framed VR environment where the model can be turned and viewed in perspective. A click on one of the pieces of the model in this information the VR environment leads to specifications and manufacturing information about the materials of its construction. The user accesses this information through a tool-palette to communicate with design team members. In this way, the team can coordinate the document's development, review progress, and make changes to the information system. This breaks the notion of a construction document as an object-of-exchange and suggests the use of the computer as a medium of communication that facilitates the design and construction process.

title A World of Data: An Animated Construction Information System as a Virtual Hypergraphic Environment
source Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 267-274
summary This paper describes research on an animated construction information system organized as a hypergraphic virtual environment. The user enters this environment to interact with the information it contains. A matrix of cubes sits as the gateway to an array of data chambers that give this information its virtual form. A mouse click on one of these cubes leads to a three-dimensional interface that is a simulation of the object to be constructed. Reflective-transparent panels surround the simulation and display two-dimensional projections of its pieces. These panels capture projections of slices through the pieces of the object represented by the simulation. Below the zero plane are slices of floor framing, foundation, excavation, utilities, and soil conditions. Above are ceilings, framing, and roofing. To the sides are finishes, wall framing, fixtures, and elevations. This immersive virtual environment extends as an array of data chambers partitioned by the suspended reflective-transparent panels. Pathways around these partitions lead to secondary chambers that contain sub-simulations of the plumbing, electrical, and HVAC systems. Design-team members access these chambers to coordinate the document's development, review progress, and make changes to the information system. The result is a WORLD of data where graphic information defines both space and time. This breaks with the notion of a construction document as an object-of-exchange and suggests a new focus for the use of computers in the design and construction process.

title PCIS Revisited: A Visual Database for Design and Construction
source Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 372-379
summary This paper presents research on a piece-based construction information system called PCIS(pronounced “pieces”) first published as a visual information concept at ACADIA’96, Tucson. After more than five years of development it has evolved into a multidimensional visual information system for design and construction. It includes a piece-based anatomical construction model layered according to a work breakdown structure; a dataTheater that surrounds the model as an index to plans, elevations, sections, and details; and a dataWorld with cameras fixed to the intersections of its latitudes and longitudes to add context and perspective. A standard services matrix (SSM) controls layer visibility and camera settings. PCIS can be “played” to access archived resources; support design development, analyze and resolve preconstruction conflicts, and coordinate construction activities. Current research will be used to demonstrate how PCIS might be valuable to increase the potential for technical cooperation, collaboration, and communication by literally aligning the points of view of architectural, engineering, and construction methodology.
